Title: Sample size calculations for clustered and longitudinal outcomes
Abstract: Correlated outcomes commonly occur in biomedical and health service research. Examples include repeated measurement studies, clustered outcome studies such as dental studies, ophthalmologic studies, and community intervention studies. The correlations among observations must be taken into consideration in the design due to the potential association for observations within a cluster. I present parametric and nonparametric methods to calculate sample sizes and powers for studies with correlated outcomes. Design and analysis of correlated outcomes will be illustrated using examples from studies of diagnostic sensitivity and specificity, community intervention studies and repeated measurement studies.
